T0 ALLv WIIOM IT MAY CONCERN;

Be it known that I, CLARK M. TERRELL, of Oskaloosa, in thecounty of Mahasla, and State of Iowa, have invented an improved Hay-Gatheror, Hay-Tcdder, and Hay-Shocker combined; and I do hereby declare that the following is n. full, cle ar,and exact-description of the same, reference being had to the annexed drawings, making part of thislspccification, in which- Figurel 1 is a perspective view: l

vFigure 2 is a side elevation with the wheel removed, and

i The-object of this invention is a machine which may be used either for gathering hay` and shocking" tion the machine, or for a. tedder for turning hay upon the ground; and it consists in a novel arrangement of mechanism for gathering the hay,` and in combining with the gathering mechanism a hinged platform, iup

`'which the hay as gathered may be shocked by a person Standing upon the machine, and the shock, whennlade, .may be deposited upon the ground in its completedform by the operation of gravity merely.

` The/following description will enable a person skilled in the art to manufacture and operate this machine.`

A is a cylindrical shell. hung from the main frame, which, with the forward` movement of thewheclsB, is caused to revolve in-a direction the reverse of that of the Wheels. Gis `a ratchet-wheel and pawl, so` connected with the wheels B and their axles that the axles shall turn when thc'wheel is moving forward,andithe wheels p .shall turn on the axle when the nia-chine is being backed. The spur-wheel D is fastened to the axle, and with its` revolution communicates motion to the pinion E on the shaft of the cylinder A.

The cylindrical shell A is 4pumztured with a series of holes', A', arranged `inlrows longitudinally with the cylinder'. The elevating teeth F are hung on the inner side of the shell A upon rods passing from end` toeud` of thecj'linder, upon which they cscillate freely. They are bent, as `shown-in iig. 3, the ends projecting through the holes A', and the part projecting being' curved, as there shown. These teeth, when projected,` l

perform the fun-:tion of raising the eut grass from the ground and carrying it .over the cylinder `with its revolution, discharging it upon the platform Gr. i

The sets of teeth are successively retracted, to enable them to pass `under thc platform by means of vthe l crank-rods H, shaped as shown in fin'. '4, and hung on the heads o the cylinder. Thelheads may he closed or open, the cranlerods, in the latter case, passing into the arms. The end Hf passes through the head or arm.`

and is bent ut right angles, and again bent at right angles at the point, so as to have a horizontal projection,

which, with the revolution ot' the cylinder, is carried against the Aower side of the eurvedfcam I, which causes` the crank-rods H to turn against the teeth F, retracting them within the, holes A. As they descend they fall hy their own gravity as soon as the crank-rod is released from the cam.

When thc hay is delivered upon the platform (r it-is gather-et` "upon a fork by the attendant standing upon the platform, and deposited in the i`orm of a shock upon the platform K. This platfermK is suspended upon a shaft attached to the t'i'amc L, su rs to permit the oscillation of the platform. It consists of n. framework, from which project the teethd K', the lutter being curved upwards, as shown in lig. 2. This form slessentialfor keeping the shock in position until discharged iu the manner to be described. The platform is sustained in a horizontal' osition l) f rods lll which asesino' throueh the frame are hnnfr from sn'ins N. These s rin s ma .l i 1 l c c: 2 C D l l he of steel,A rubber, coils of wire, er any other suitable material. tlhe tension of' the springs must be suilcient to sustain the weightof a shock of hay ol' the ordinary or designed size, und to allowthe platform tn descend when the limited weight has heeny place-d upon it. When the shock is completed, if it is not heavy enough to hear down the springs, the operator may, h y pressing upon its top with his fork7 hear down the` springs N, Cil-Uifjg the platform to swing upon its bearings until the teeth K `are brought upon the ground, when the shock will be slid oli', remaining standing upon the stubble as the teeth pass from under it, the platformimmediatcl returning to its normal position. l

Thin metallic hands O are attached to themain frame, surroumling andtin'closc proximity to the ends of` the cvlindrieal shell A. Thse hands serre to se :irate the hir that is hcinfr elevated from that remaiuin `on c p il y p" -tially as and for the purpose set forth.

the grounch/and by their use the hay is prevented from Wedging between the cylinder and the frame and clogging the action of the machine.

An elevating appara-tus may be attached to the machine for carrying the hay from the cylinder and dropping it upon the platform K, when it is designed to bunch the hay instead of shocking it on the machine.

The platforms G and K I propose to connect in such manner with the frame that they may he detached and the cylinder then used alone as a tedder for turning the hay.

What I claim as my invention, and desire to secure' by Letters Patent, is-

1. The mode of reti-acting the teeth F, by means of the crank-shafts H, in combination with the cam I, substantially as set forth.

2. In combination with the cylindrical shell A and teeth F, a receiving-platform for sustaining the operator informing a shock upon the hinged platform K, substantially as set forth.

3.' In combination with a hay-elevating cylinder A and receiving-platform G, the hinged discharging platform K, arranged to operate Substantially as described.

4'. The platform K, hinged to the machine and supported by a spring, so arranged as to discharge the shock by the action of gravity merely, substantially as set forth. I

5. The combination of the hingedplatforln'K with curved teeth' K and the supporting spring N, substan- 6. In combination with the revolving cylindrical shell A, the band O, arranged to operate substantially in the manner and for the pui-pose set forth.

7. S0 attaching the platforms Gr and K that they may be detached and the machine be converted into a tedder, substantially as set forth. Y Y

In testimony whereof I have signed my name to this specification in the presence of two subseribingwitncsses.
